EI1KNH/B Irish 8m beacon on 40.013 MHz WSPR

Tim, the beacon keeper, has recommended I try 8m WSPR RX. 

The WSPR sessions are several times an hour and WSPR works with very weak signals. I am on 8m WSPR now, but a bit uncertain about the 2 minute cycles. This may only work with tropo and certainly not work with MS or aircraft.  I may try from now and over the weekend. 

The beacon is only active from 0600-2400, but I am not sure if this is local time or GMT. With tropo, I would have suspected my best chance would be early in the morning?

If this fails (I have low expectations) I may try MSK144 in an MS shower.

  1. The problem with WSPR is that the signal needs to be there for the entire 2 minutes, particularly right at the start of transmission or no decode takes place, fine for tropo etc but not MS.

  2. I am not too hopeful about WSPR, but it is worth a try. Tropo might just work. I totally get that this will NOT be good for MS or aircraft. 73s Roger G3XBM.

  3. Read your comments and so turned my rig on this morning just after 8 o’clock.

    Decoded the beacon on WSPR at 07:34 and 07:54utc, both at level -27dB.

    I’ll leave the radio on for the rest of the day and see what happens.

    Using FT-817ND and end-fed wire 20m long, about 2m above ground.

  4. Some more decodes of WSPR. I have now set up to report automatically to the WSPR Net site, and am going to leave the rig monitoring the beacon continuously for at least the next 24 hours.
